IMPROVEMENT IN HEAD-RESTS FOR CAR-SEATS.

Specification forming part of Letters Patent No- 212,167, dated February 11, 1879; application filed March 30, 1878.

To all whom it may concern:

Be it known that 1, JOHN 0. Emma, of Hornellsville, New York, have invented an Improvement in Head-Rests for Car-Seats, Chairs, &c., of which the following is a specification: g

It is the object of this invention to produce a portable head-rest, which is adapted to be expeditiously applied and firmly secured to the back of a railroad-car seat or similar chairback, and capable of being packed up in small compass for convenient carriage when not in use 5 and the invention consists in a construction and combination of parts whereby the same is effected.

The practical embodiment of this invention is illustrated in the accompanying drawings, wherein Figure 1 is an elevation of a railroad-car seat with head-rest adjusted thereon. Fig. 2 is a side view of the principal parts of the headrest as adjusted together. Fig. 3 is a reduced rear elevation of the same. Fig. 4 shows the operation of the clamp, and Fig. 5 shows the various members of the head-rest detached from each other and associated together for convenient carriage.

. The essential elements of my improved device are a rest or pad, A, for the head, two clamp-bars, 2 3, that are connected together by a tenon and socket, and which embrace the back of the seat, and a clamp, 4, which secures said clamp-bars in place.

The pad A will, of course, be provided with a rigid block or frame-work, B, to which will be affixed the cushion or padding constituting the said pad A, which is properly curved to suit the contour of the human head. This block or frame-work B will have a clamping thumb-screw, G, or a similar device, for connecting it with the clamp -bar 3, which bar will preferably be provided with a slot, 5, in which the shank of the screw 0 lies, which arrangement provides for the adjustment of the pad A. Any other construction of parts which permits this adjustment of the pad may, of course, be provided.

The clampbars 2 and 3 are made of any suitable metal, preferably wrought-iron, and

are so shaped that when connected together by entering the tenon 6 on the one into the socket 7 in the other the pendent ends will stand at the proper angles to adapt them to embrace the back of a car-seat or chair, as in Fig. 1. At properpoints upon their exterior faces these bars 2 3 are furnished with ratchets 8 9, into which the teeth of a clamp, 4, may

engage.

The several parts of this device may be detached from each other, in order that they may be packed in such relation to each other as to form a convenient package for carriage, as is shown in Fig. 5.

Then it is desired to use this device the rest A is adjusted in the slot 5 of the clamp bar 3, and there secured by means of the clamp-screw O, and then tenon 6 of the clampbar 2 is entered into the socket 7 of the clamp bar 3, so that said clamp-bars thus adjusted spread apart, as in Fig. 2, and are adapted to fit upon a chair-back when placed thereon, as in Fig. 1.

The clamp 4, which is simply a square metal collar, having been placed loosely over both of the clamp-bars, is then forced downward until it presses the bars toward each other to such a degree as to cause them to tightly clamp upon the opposite sides of the chair-back, and thus be securely held thereto, thus rigidly holding the rest A in a position to support the head of a person. 1

In order that the clamp may not slip or otherwise "become displaced, the bars 2 3 are provided with the ratchets 8 and 9, into the teeth of which the inner wedge-like surfaces of the clamp 4 engage, as in Fig. 4, and there by lock the clamp in its position of adjust ment.

This improved head-rest is exceedingly sim ple and inexpensive, being composed. of few parts, and is, moreover, of a very advantageous construction, since it may be taken apart, packed in a small space, and conven= iently adjusted in place for use.

\Vhat I claim is 1. A portable head-rest for the backs of seats, consisting of the pad A, clamp-bars 2 3, connected together by tenon and socket, as

Enron.

described, and adaptedto embrace the seat- In testimony whereof I have signed my back, and a clamp-ring, 4, substantially as dename to this specification in the presence of scribed. two subscribing Witnesses.

2. The combination, with the rest A, of the JOHN O. ADSIT. bar 2, having a tenon, 6, and ratchet 8, the Witnesses: bar 3, having a socket, 7, and ratchet 9, and Gr. 1 RIsHEL, the clamp 4, substantially as described. A. B. VVOODARD.
